BUGGY CHAMP PINION PITCH

[FLEXUS]

Hi guys

what size pitch are the gears used in the 2009 buggy champ?

Gonna order a steel replacement before i start my build.(any recommendations?)

also just had a look at the instructions for the gear ratio,s and all it says is high/low ratio setting.

does anybody know what they are as im thinking of buying a new motor.might buy another superstock BZ ratio 9:1-11:1

or just a sports tuned and keep the standard TEU 104 ESC.(any motor recommendations?)

cheers Karl

These are 0.6 module, either 15 tooth or 20 tooth. RRP1115 and RRP1120 (Robinson Racing - US) or ARW0600-15 and ARW0600-20 (RW Racing - UK).

Good day TA-Mark

nice one for the reply mate.

I'll grab the final drive ratios for the two gearing options from the RC workshop tomorrow. Too cold outside in the wee hours of the morning here.

EDIT: Found them on the Tamiya website. 15/70 is 9.3:1 and 20/65 is 6.5:1.

^{Dont the kit come with a steel 15 tooth pinion already?}

^{My sand scorcher did.}

[Grastens]

I think the 15T pinion is steel and the 20T pinion is aluminum; both are in the kit. My 20T pinion definitely wore faster than the 15T...

[TA-Mark]

I'm very sure the kit supplied 15 tooth is steel. The 20T is aluminium butter. I didn't use them in my SRB It's 19T/82T 0.5mod gearing.

Alright mate

nice one Mr R/C wikipedia. .

is there a big difference in top speed/acceleration between high/low ratio when using the standard motor?

especially with a five tooth pinion difference.

That I don't know. I ran mine once with a silvercan on 15T/70T, then tore it to bits, made a gear diff, modified a DF03 slipper clutch to fit and then bolted in a MambaMax 4600Kv brushless.

Since the five teeth difference applies to both the pinion and the spur, I am told it actually does make a noticeable difference.

Running my Buggy Champ with the TEU-101BK and a silver can with a NiMH battery, I noticed a lot more wheelspin with the 15T/70T combination than the 20T/65T setting, though top speed was not as easily noticeable. Eventually I did find that the lower ratio was faster overall, if only by a few km/h,

That I don't know. I ran mine once with a silvercan on 15T/70T, then tore it to bits, made a gear diff, modified a DF03 slipper clutch to fit and then bolted in a MambaMax 4600Kv brushless.

A great reason if I ever saw one!

I,ve not opened the parts blisters yet.i,ll check it out.

Alright mate

thanks for the input.

was that a big difference in speed/acceleration TA-Mark?ha ha :D

Just a little. Hahahaha (2S Lipo too).

Just a thought you can go with the 15 tooth and try one of the $11.00 cheap duratrax photon speed 2 twenty turn motors in it if you think the speed is to slow stock...and with a faster motor like the 20 turn you would want to go with the smaller pinion gear anyhow.

Alright Shen

yeah if i decide to upgrade the ESC i might go down the duratrax 20 turn route.(i know you highly rate them)

not sure which way im gonna go yet mate as i,ve just read a thread though which mentions the buggy champ is designed only for the silvercan unless you modify the way the motor is held in.

I might be wrong but I think the re-release had the mod all ready done so that you can swap motors, there was two pins in the gearbox that needed removing? or I could be making it up? not sure?

Hi Karl the duratrax should drop right in it's just like the tamiya stock can... I have alot of tamiyas runing the 20 turn duratrax motor all using the stock tamiya kit esc's i had no problems at all with them.
